Using commas for decimal separator

[skalee]

Most English-speaking countries use dot for decimal separator, but many other countries use comma instead. The problem is that AsciiMath grammar allows only dots:

• https://github.com/asciimath/asciimathml/blob/c70e24937361e3f71a171c0f56952e18719d3197/ASCIIMathML.js#L52

(Actually it seems that this may be configurable, but at least interactive renderer on http://asciimath.org recognizes only dots)

@ronaldtse what to do with that? Should we replace commas with dots, or should we keep these commas and produce somewhat "broken" expressions?

Also, https://www.electropedia.org/iev/iev.nsf/display?openform&ievref=112-01-28 uses commas in English definition. This may be an error that IEV should be notified about.
